uB31 / uB41

uB31/41: DC Voltage Field Input Module

• Field Input: ±1V to ±60V ranges

• Host Output: 0-5V or ±5V ranges

The uB30 and uB40 models condition and convert a low-level DC voltage field input signal to a scaled 0-5V or ±5V output. The uB30 has more filtering for low-band applications, while the uB40 relaxes filtering for higher speed applications. uB30 modules are recommended for noisier environments where conversion speed is less of a concern. uB40 modules drive a faster response, but with less filtering for noise.

Description

Acromag’s microBlox® uB Series I/O modules offer a compact, high-performance solution for interfacing sensors and field devices with data acquisition systems. uB signal conditioning modules are ideal to isolate, filter, convert and amplify a wide variety of signal types for test, measurement and control systems. Just plug uB modules into 4, 8, or 16-channel backpanels in any mix for a high-density analog I/O interface. Channel-to-channel isolation provides optimal noise and surge protection from ground loops, spikes, and high common mode voltages.

Bluetooth® wireless technology versions enable configuration using a smart phone or tablet. Acromag’s Agility™ app, available for Android™ and iOS® mobile devices, helps you vary input/ output ranges and scaling to your specific application. The Agility app can also set an alarm output function with a setpoint limit and deadband. Other app functions include polling inputs, trending values in a sharable chart, updating calibration, and diagnostic troubleshooting.

For cost-sensitive projects, a commercial-grade version is available (-CG models). These units offer similar performance, but over a limited temperature range and lack hazloc approvals.

Safety Isolation: Field channels are individually isolated field channel-to-field channel and from the field to the host I/O bus (host group includes 5V power) for commonmode voltages up to 250V AC, or 354V DC off DC power ground, on a continuous basis (will withstand 1500VAC HIPOT/dielectric strength test for one minute without breakdown). This complies with test requirements of ANSI/ISA-82.01-1988 for voltage rating specified.
